Chromium chloride anhydrous

PROP Red-violet flaky crystals. Mp 1152°, bp 1300° (subl). Insol in cold H2O sltly sol in hot H2O. IDLH 25 mg/m [as Cr(III)]. SYNS CHROMIC CHLORIDE CHROMIUM(III) CHLORIDE (1 3) CHROMIUM CHLORIDE, anhydrous CHROMUM TRICHLORIDE C.I. 77295 PURATRON-IC CHROMIUM CHLORIDE TRICHLOROCHROMIUM... [Pg.363]

Chromium (II) chloride (anhydrous) [10049-05-5] M 122.9, m 824 , d]" 2.75, Obtained from the dihydrate by heating in vacuo at 180°. It is a very hygroscopic white powder which dissolves in H2O to give a sky blue solution. Stable in dry air but oxidises rapidly in moist air and should be stored in air tight containers. It sublimes at 800° in a current of HCl gas and cooled in the presence of HCl gas. Alternatively it can be washed with air-free Et20 and dried at 110-120°. [Inorg Synth 3 150 1950.]... [Pg.413]

Assemble an apparatus (see Fig. 61). Place the dry beads into a porcelain or quartz tube and perform chlorination at 750-800 °C during one hour. Ghromium(III) chloride can sublime, therefore see that the tube outlet is not clogged by the product. Cool the apparatus in a stream of chlorine. Extract the beads from the tube and mechanically separate the chromium chloride formed on their surface from the unreacted charcoal. In what other ways can anhydrous chromium(III) chloride be obtained ... [Pg.224]

When the apparatus has been flushed, a boiling solution of 16 g. (0.20 mol) of anhydrous sodium acetate dissolved in 35 ml. of water is added through E A slow nitrogen flow is maintained, and a solution of 9 g. (0.034 mol) of chromium(III) chloride 6-hydrate in 15 ml. of 0.4 N sulfuric acid is poured into the top of the redactor. The rate of flow of the chromium solution can be controlled by stopcock B. If too fast a rate is used, there is a possibility of incomplete reduction. Distilled water is poured after the chromium chloride until the effluent is only slightly colored by chromium. This requires approximately 125 ml. [Pg.128]

Grignard synthesis is the method that Hein [9] used first to synthesize organochromium compounds in 1919. Anhydrous chromium chloride reacts with PhMgBr in an ether solution, forming an inflammable, paramagnetic black solid. Phenyl-chromium compound is obtained by hydrolysis of the black solid. [Pg.255]
